Manglik dosh and nivaran This dosh occurs when the placement of Mars in the horoscope is in certain houses that cause malefic influences. People, in whose natal chart Mars is placed inauspiciously, are called Mangliks.
The most famous myths about being a Manglik is that if anyone is married to a non-Manglik then the spouse is bound to die. This does not happen to everybody.
but such predicament is only true for horoscopes, which have a severely afflicted Mars. A good astrologer can do this determination.
Approximately 40% of the population are supposed to be of Mangliks.
To prevent things from going to such an extreme, the ancient sages of India recommended that the horoscopes of both the girl and boy be matched before marriage.
If the horoscopes are found compatible then only one should go ahead with the marriage. Like always prevention is better than the cure.
If a marriage is solemnized without consulting the natal charts for the presence of manglik dosha, it can lead to a lot of troubles. Suppose either or the spouse is a manglik, then the married couple is likely to suffer from various problems like unnecessary arguments and undue emotional distress without being able to pin point the cause of the same. In many of the cases the marriage tends to lead to a divorce.
